Enhancement of spin current in Fe${}_{85}$Co${}_{15}$/Ni${}_{80}$Fe${}_{20}$ bilayers via interlayer ferromagnetic coupling

A. A. Pérez Martínez, D. Velázquez Rodríguez, D. Goijman +6

We present a detailed study on how the strength of the interlayer magnetic coupling on Fe${}_{85}$Co${}_{15}$/Ni${}_{80}$Fe${}_{20}$ bilayers modifies the spin wave behavior of this system…
